  3. 3. TOPIC SITUATION
  4. 4. HISTORY OF THE DISCOVER <ul><li>2004, University of Manchester </li></ul><ul><li>Andre Geim: physique professor </li></ul><ul><li>Konstain Noselov: Russian student </li></ul><ul><li>Other student was studying graphite </li></ul>
  5. 5. <ul><li>Way of studyng graphite </li></ul><ul><li>Substract in shelotape study </li></ul><ul><li>Discover of a new material: graphene </li></ul><ul><li>Study of it structure, propietes, possible applications… </li></ul><ul><li>2010: Andre Geim and Konstain Noselov won the Nobel Prize </li></ul>HISTORY OF THE DISCOVER
  6. 6. WHAT IS IT? Gra phene is an allotrope of carbon. An allotrope is the property of some chemical elements to exist in different molecular forms .
  7. 7. STRUCTURE <ul><li>Plane laminates </li></ul><ul><li>Hexagonal structure </li></ul><ul><li>One atom in each vertex </li></ul><ul><li>Graphene sheets stracket together form graphite </li></ul>
  8. 8. PROPERTIES <ul><li>First two-dimensional material </li></ul><ul><li>Transparent </li></ul><ul><li>Great conductive of heat and electricity </li></ul><ul><li>High elasticity and hardness </li></ul><ul><li>Resistance </li></ul><ul><li>Reacts chemically wit other substances </li></ul><ul><li>Light and flexible </li></ul><ul><li>Reduces Joule effect </li></ul>
  9. 9. WAYS OF OBTAINING We can find graphene in: Pencils Diamonds
  10. 10. WAYS OF OBTAINING <ul><li>Expholiate graphite with adhesive tape </li></ul><ul><li>The majority of the final product: graphite </li></ul><ul><li>The minority: graphene </li></ul>TO OBTAIN GRAPHENE IN SMALL QUANTITIES:
  11. 11. TO GET A SUCCESSFUL TECHNIQUE : <ul><li>Carefully selection the initial graphene material </li></ul><ul><li>Using claning surfaces </li></ul>HOW TO INDENTIFY GRAPHENE: <ul><li>Optical microscopy: detects the 2D crystals </li></ul>
  12. 13. APPLICATIONS <ul><ul><ul><li>Screens </li></ul></ul></ul><ul><ul><ul><li>Computing (processors) </li></ul></ul></ul><ul><ul><ul><li>Memristors </li></ul></ul></ul><ul><ul><ul><li>Electronic materials </li></ul></ul></ul>Graphene applications haven’t been determined yet. Although some experts have pointed if futures uses:
